Soldier accused of conspiring to kill wife pleads not guilty

HONOLULU (AP) — An Army medic in Honolulu pleaded not guilty Thursday after a federal grand jury indictment charged him with conspiring with his lover to kill his wife.

Sgt. Michael Walker was arraigned on murder and other charges in the death of Catherine Walker, who was found stabbed multiple times in their home at Aliamanu Military Reservation last November.

Co-defendant Ailsa Jackson was arrested in April in Indiana and extradited to Honolulu. The indictment accuses Jackson of using a key left outside the Walkers' back door to enter the home, grabbing a knife from the kitchen and killing Walker in a bedroom where she slept.

Jackson also has pleaded not guilty, but court records filed after Walker's arraignment indicate she will change her plea on Nov. 20.

The indictment alleges Michael Walker and Jackson exchanged emails and text messages about carrying out the killing at a time when he would be at work and making it look like a burglary.

Assistant U.S. Attorney Jill Otake said the government won't seek the death penalty. Hawaii doesn't have the death penalty, but it's possible in federal cases.
